<p class="MsoNormal">That is what failure_routes are for. You can “catch” the 404 in a failure_route and choose somewhere else to attempt to send the call. You don’t have to just send back the response all the time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But what I think David was trying to ask is just why you are combining the lb_start and lookup calls always into a single if statement. This is very confusing and will end up with lb_start and/or lookup being called more than once in many
cases. I don’t use the load_balancer module, but I think calling lb_start multiple times in the same call/transaction may skew the load balancing stats.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In your code snippet, you are even calling both lb_start and lookup again within if legs where their return values have already been checked.<o:p></o:p></p>

<p class="MsoNormal">That's fine, if 555 is an extension, but if it's (for this example) a PSTN number (or a all-else catch all, like I'm trying to achieve) thats not OK because I get a 404 rather than it getting routed to the load balancer.<o:p></o:p></p>

<p class="MsoNormal">hi,<br>
<br>
perhaps this can be solved with a failure route and or a check status<br>
but i dont know and it would be nice if i could do it without it.<br>
<br>
no matter how i write the script, either a uac to uac call goes to the<br>
load balancer or the load balancer is stuck with a 404 reply from the<br>
script or uac to uac works but when one end is not registered it goes<br>
to the load balancer instead of getting a 404.<br>
<br>
i've tried failure routes and get the same problem. here is a snippet.<br>
<br>
if (!lb_start(1,"pstn")) && (!lookup("location","m",)) {<br>
lb_disable_dst();<br>
#route(relay);<br>
#send_reply(404,"No user or gateway");<br>
if (lb_start(1,"pstn")) {<br>
send_reply(500,"SIPSIPSIPS");<br>
# t_relay();<br>
exit;<br>
}<br>
# exit;<br>
} else if (lookup("location","m")) &&<br>
(!lb_start(1,"pstn")) {<br>
lb_disable_dst();<br>
route(relay);<br>
exit;<br>
} else if (lb_start(1,"pstn")) &&<br>
(lookup("location","m")) {<br>
lb_disable_dst();<br>
route(relay);<br>
exit;<br>
} else if (!lookup("location","m")) &&<br>
(!lb_start(1,"pstn")) {<br>
send_reply(404,"Not Found");<br>
exit;<br>
} else if (lb_start(1,"pstn")) &&<br>
(!lookup("location","m")) {<br>
# #lb_disable_dst();<br>
if (!lookup("location","m")) {<br>
route(relay);<br>
exit;<br>
}<br>
if (lookup("location","m")) {<br>
lb_disable_dst();<br>
route(relay);<br>
exit;<br>
}<br>
}<br>
<br>
thanks in advance,<br>
